When do Cockapoos Stop Growing?

September 24, 2022

As a mixed breed made by breeding a Cocker Spaniel and a Poodle, the Cockapoo is an interesting dog breed which offers the best of both of these popular dogs.

And if you have a Cockapoo puppy, you may be starting to wonder when Cockapoos will stop growing. The adult size a Cockapoo grows to be can differ by quite a bit depending on the type of Cockapoo you have.

There are four types of Cockapoos you could get. Options include Teacup, Toy, Miniature, and Standard/Maxi Cockapoos. Each with its own size and weight range. If you think you have a Standard Cockapoo and it turns out you have a Toy Cockapoo, you may be a bit confused when they don't appear to be growing a lot.

This could leave pup parents wondering if there was something wrong with their dog if they are still a bit on the small side after a few months. However, it would be perfectly natural in that case.

In this article, we will be looking at what age a Cockapoo will stop growing along with what factors could play a role in your dog's adult size.

What Age do Cockapoos Stop Growing?

Cockapoos reach their adult size between nine and 12 months old.

By nine months old, it is unlikely your dog's height will change, though their weight will continue to for the next three months plus. If you have a male Cockapoo, they'll likely still be developing a bit more after this too. Males need to bulk out a bit more with some muscle.

How do I Know my Cockapoo is Fully Grown?

There are a few ways you can work out if your Cockapoo is finished growing.

First, you need to know how the type of Cockapoo you have as each of the four types of Cockapoo is different sizes, how big each should be at different times will differ slightly. Make sure you are using the correct measurements to see when your dog is the right size.

We have an article on how big Cockapoos get if you want to know what size they should be. You can use this data to measure your Cockapoo. If they are around the right size roughly, then your Cockapoo is very likely about fully grown.

Your dog's age will also play a role here as they are usually fully grown at around one year old.

It is also worth mentioning that as the Cockapoo is a mix of two dog breeds (the Cocker Spaniel and Poodle), there is no specific breed standard which says what size your dog should be. All we can do is work from the averages on what previous Cockapoo owners have observed.

What Can Impact the Size of an Adult Cockapoo?

Now you know how large a Cockapoo should be as an adult, let's talk about what can impede your dog's ability to grow.

There are actually quite a few factors which can influence this, maybe more than you would think. The main ones are the type of Cockapoo, nutrition, health issues, exercise, genetics, and just plain luck!

While some of these factors you have no control over there are some that you can influence. For example, it is quite easy to make sure your dog eats a good diet as well as gets enough exercise to stay in good shape.

You can also take your dog to the vet for regular checkups to make sure you get ahead of any other problems.

What Should I do if I Think my Cockapoo Isn't Growing Properly?

If you think your Cockapoo isn't growing at the correct rate the first thing to do is relax, it is very likely that your dog is developing just fine. All dogs grow at their own rates, some are bigger and some are smaller.

Next, book your dog into the vet for a checkup to ensure everything is still okay. Your vet should be your first port of call as they will be able to let you know if this is just in your head or if there is something that will need to be addressed.

Conclusion

Typically Cockapoos stop growing in height at around nine months old and will continue to grow to their adult weight until around 12 months, and longer for male dogs.

How much exactly this looks like will vary quite a bit depending on the type of Cockapoo you have. Make sure you know how much your Cockapoo is supposed to grow before making a decision on if they are growing as they should or not.

Little dogs reach their full size quicker than big dogs. This is because they have a lot less growing to do as a puppy. This means you will see bigger steps forward in your dog's growth early on in their lives.

Hopefully, you have found this guide to how long it takes Cockapoos to stop growing helpful.

As anyone who has had a dog since being a puppy will tell you this time flies past soo quickly. Make sure you spend lots of time with your Cockapoo while they are still a cute little pup!
